ABSTRACT:
The invention pertains to the art of ferrous metallurgy, and more particularly, to a multichambered steelmaking apparatus and to a method of steelmaking. A multichambered steelmaking apparatus contains smelting chambers communicating with each other through their upper portions. Process input ports are provided in the chamber side wall, and the smelting chambers are provided with gas-oxygen burners installed on the walls of the smelting chambers facing each other. A method of steel making employs the apparatus in a unique manner. During operation, the smelting chambers are tilted in the direction of the input port and during the discharge of steel they are tilted in the direction of the outlet. During the melting stage carbon monoxide (CO) is afterburned by gas-oxygen burners forming carbon dioxide (CO) in the exit gasses supplied to the gas exhaust system through the coaxial chamber. A portion of a slag from the previous heat is retained.
